- Executive summary:
Method:
Decomposition was determined by means of Differential Scanning Calorimetry according to the guideline OECD 102 corresponding to the internal method SOP-STR 028.
Observation:
Esothermic effect was observed between 272 and 405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g). Release of imbibition solvent was observed between 25 and 140 °C
Results:
Decomposition of the tested substance was observed between 272 and 405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g)
Reference
Esothermic effect: 272 -405°C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g).
Release imbibition solvent: 25-140 °C.
Decomposition: 272 -405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g).
Description of key information
Decomposition = 272- 405 °C
Key value for chemical safety assessment
Additional information
Decomposition was determined by means of Differential Scanning Calorimetry according to the guideline OECD 102 corresponding to the internal method SOP-STR 028.
The tested substance decomposes before boiling between 272 and 405 °C (onset = 257.4°C; enthalpy = 40.8 J/g and onset = 325.9°C; enthalpy = 64.0 J/g).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
